An X-ray diagnosis apparatus includes an X-ray tube for projecting X-rays onto a subject, a two-dimensional X-ray detector for detecting X-ray signals from the subject, an image processing unit for generating image signals to perform image display of an image represented by the X-ray signals received from the two-dimensional X-ray detector, and an image displaying unit for displaying the image. The X-ray diagnosis apparatus further has a noise eliminating unit for generating noise correction signals from the X-ray signal of two scanning lines that are adjacent to each other out of a plurality of scanning lines of the two-dimensional X-ray detector and for eliminating noise in an X-ray signal of the scan lines by using the noise correction signal.
